The toxicity and oxidative stress of TiO2 nanoparticles in marine abalone (Haliotis diversicolor supertexta)
TL;DR: It is demonstrated that, although nTiO2 is not acutely toxic to abalone, it does exert oxidative stress on abalone.

TL;DR: It is likely that one of the adaptation mechanisms of protozoa to nCuO was lowering membrane fluidity by the inhibition of de novo synthesis of fatty acid desaturases by the effects of nanoparticles on the membrane fatty acid composition.
Journal ArticleDOI
Effects of nanoparticle zinc oxide on spatial cognition and synaptic plasticity in mice with depressive-like behaviors
TL;DR: Investigation of effects of nanoZnO on animal model of depression indicated that model mice showed disrupted spatial memory and LTP after LPS injections and the behavioral and electrophysiological improvements after nano ZnO treatment suggested that nanoZNO may play some roles in CNS of mental disorders.
Journal ArticleDOI
Evaluation of the phytostabilisation efficiency in a trace elements contaminated soil using soil health indicators
TL;DR: Under semi-arid conditions, the use of compost and pig slurry with A. halimus is an effective phytostabilisation strategy to improve soil health of nutrient-poor soils with high TEs concentrations, by improving the habitat function of the soil ecosystem, the reactivation of the biogeochemical cycles of essential nutrients, and the reduction of TEs dissemination and their environmental impact.
Journal ArticleDOI
Comparative toxicity of nano-ZnO and bulk ZnO suspensions to zebrafish and the effects of sedimentation, ˙OH production and particle dissolution in distilled water
TL;DR: The results showed that dissolved Zn(2+), from nZnO and bulk ZnO in suspensions, were toxic to zebrafish, while the aggregation and sedimentation of nNnO suspensions reduced the toxicity of nZNO.

Nanotoxicology: An Emerging Discipline Evolving from Studies of Ultrafine Particles
TL;DR: Results of older bio-kinetic studies with NSPs and newer epidemiologic and toxicologic studies with airborne ultrafine particles can be viewed as the basis for the expanding field of nanotoxicology, which can be defined as safety evaluation of engineered nanostructures and nanodevices.
Journal ArticleDOI
Probing the Cytotoxicity Of Semiconductor Quantum Dots.
TL;DR: This work found that CdSe-core QDs were indeed acutely toxic under certain conditions and modulated by processing parameters during synthesis, exposure to ultraviolet light, and surface coatings, and suggests that cytotoxicity correlates with the liberation of free Cd2+ ions due to deterioration of the Cd Se lattice.
